Constructor is used to initialize an object. In other words, constructor provides memory to an object. Without initializing an object we can’t use its properties.

ď ˝

But there is no need to define or declare a default constructor in Java. The compiler implicitly adds a default constructor in the program if we have not declared or defined it.

The only purpose of the constructor is to set a variable's default value, which will be zero anyway. This default constructor will be implicitly declared and created by the compiler.
